Participants as requestors using a requesting network element request one or more tokenization processors to generate tokens that represent a sanitized version of data such that the resultant tokens are amenable to comparison across participants. As circumstances warrant, one or more such tokens can be submitted to the tokenization processor(s) to privately retrieve the original data. Role-based access control scope parameters and tokenization processor-specific tokenization processor secrets can be embedded into reversible tokens that remain invariant under updating of the tokenization processor secrets across tokenization processors. By another approach, role-based access control scope parameters and tokenization processor-specific tokenization processor secrets are embedded into tokens and corresponding key tokens such that upon authorized presentation of a token by a requestor, the corresponding key token is recovered so that the keying material that was used to generate ciphertext is retrievable in order to recover the corresponding plaintext.
